The Autostick carbs wore a different flange number. The jetting seems the same, though interestingly enough Ghias were jetted differently likely due to their air cleaner differences.

The autostick carb did also have a second port on the back as Joey alluded to...it is on the right hand side (back is back. This port, as Joey stated goes to the control valve using 3.5mm vacuum hose.

The universal carbs offered today would need the port drilled to be used properly. The boss is there (as it is on all the 34 pict 3's).

This link shows teh port in question.
